ANT+ and Bluetooth Compatible 4iiii PRECISION 3 power meters use both the ANT+ PWR and Bluetooth Smart Cycling Power Service standards, which makes them compatible with nearly every headunit, smartphone, or computer you wish to connect to. Check your recording device documentation for ANT+ PWR or Bluetooth Smart (also called BLE, BTLE, or BT4.0) Cycling Power Service capability. Indoor Training If the weather or climate makes riding outdoors tough, your 4iiii PRECISION 3 powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy, and more. Simply use your favourite app's connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding. 4iiii Warranty Ridden through rain storms at Strade Bianche, mud-filled cross country mountain bike races, and even tested amidst the salt spray of the ocean on Oracle Team USA's America's Cup competitors, you can be assured that your 4iiii Powermeter will be as tough as you are and is backed with an industry-leading 4iiii 3-year warranty. All 4iiii Powermeters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty. Technologies: Accuracy in 3D: Not everyone has the perfect pedal stroke. With +/- 1% accuracy, 4iiii is the only crank-based power meter to use 3 strain gauges to measure all forces in your pedal stroke. Ultra Low Profile: With an ultra low profile design, the PRECISION 3 is compatible with more bike frames than ever before. Indicator Light: At a glance, you can now see when your power meter has turned on, performed a successful Zero-offset, or has a low battery. Although, don’t expect to see that low battery indicator for a while! Waterproof: Based in the foothills of the Canadian Rockies, we were tired of training tools not designed to work in our tough environment. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions. ANT+ & Bluetooth: Get the same numbers training inside and outside. The PRECISION 3 Powermeter is both ANT+ and BLE compatible so you can use it on your preferred head unit and favorite indoor training app. 3 Year Warranty: A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all 4iiii Powermeters are backed by an industry leading 3-year warranty. In The Box: Once your ride-ready PRECISION 3 powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. Connect a headunit or computer, and you can start riding with power! Manufacturer's Part Numbers: PML300-S21B00A Black 170mm PML300-S21D00A Black 175mm

Engineered for extreme accuracy during your training sessions, these components feature a single power sensor on the left pedal. Designed with breakthrough technology, this version's power meter uses IAV Cycling Dynamics and is mounted directly on the left pedal for real balance data and not estimates. By using the integrated gyroscope, the Favero Assioma Uno Power Meter Pedals also provide advanced pedal metrics for an incredibly detailed analysis of your pedalling. Coming complete with both Bluetooth and ANT+ connectivity, as well as up to 50 hours of battery life, the Favero Assioma UNO Power Meter Pedals are a great choice of upgrade for road bike riders who want to improve their performance. IAV Power System Many power meters calculate your power output using the Average Angular Velocity (AVG) per rotation, instead of the instantaneous Angular Velocity (REAL) value: this may introduce an additional error, up to 4.5% compared to the declared accuracy. With the Favero Assioma Uno model, thanks to its exclusive IAV Power system and an integrated gyroscope, the actual instantaneous angular velocity is measured to guarantee the same ±1% degree of accuracy with any style of pedalling, even with oval chainrings. Automatic Temperature Compensation Rain, snow, mud, or sweltering heat: Automatic Temperature Compensation (ATC) ensures exact, consistent watt measurements in any weather condition at temperatures between -10°C and 60°C. Waterproof, Resistant and the Lightest Ever Made The lightest and most compact pedal-based power meter made by Favero: with no protruding elements, it does not interfere with the pedalling. Not even when cornering. Protected by a bi-component resin block, the power meter sensor is extremely resistant to shocks and fully waterproof. Item Top Features Continued: Temperature Compensation: -10°C / +60°C Water Resistance Degree: IP67 Q-Factor: 54mm Hardware upgrade to Assioma DUO always available Compatible Cleats: Original LOOK Kéo and Favero cleats (red and black) Bike Type: Racing, Road Made in Italy Warranty: 2 years Total Weight Per Pedal: 151.5g (battery included) In The Box: • Left pedal with power sensor • Right pedal without power sensor • Battery charger including plugs (EU, US, UK, AU) • 1 two-metre long micro-USB/USB cable with magnetic connector • 2 red cleats float 6° (LOOK Kéo compatible) • Hex key and 4 washers for the installation • User manual Technologies: Easy to Install: Install and transfer your Assioma from one bike to another just like normal pedals, easily and without extra tools. Just screw them on your bike crank arms and you are ready to pedal! IAV Cycling Dynamics: Assioma supports the advanced metrics IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, allow analyzing in details the pedaling technique and how the cyclist's position on the bike influences performances. IAV Power and Gyroscope: Unlike others, the measurements of Assioma are not affected by errors related to very irregular pedaling (eg. sprint uphill) or the use of oval chainrings. This is because Assioma is able to detect the actual instantaneous angular velocity of the pedal stroke, thus giving you the degree of accuracy of ±1% in any situation. Not only in the laboratory. Bluetooth and ANT+ SMART: Assioma communicates via Bluetooth and ANT+ with bike computers and smartphones, both Android and iOS. Accuracy and Consistency: Assioma provides accurate watt measurements with a great consistency and stability in the actual on-road use conditions and at any temperature between -10°C and 60°C. Thanks to the ATC (Automatic Temperature Compensation) too. Waterproof, resistant and light: Assioma is the lightest pedal-based power meter ever made. Thanks to its compact design, it never interferes with the pedaling. Not even when cornering. The power sensors are protected in a bi-component resin block, extremely resistant to shocks and completely waterproof. Rechargeable and Green: Assioma is the only pedal-based power meter with integrated rechargeable batteries; a single charge ensures 50 hours of use at least. Tested and Guaranteed: Favero Electronics produces in-house each Assioma and thoroughly test it individually: fully satisfying the standards required by current regulations.
